Academy-award winning actress Emma Thompson joined climate change activists in London on Friday to cap off a week full of protests against British inaction on climate change, reports Reuters.

Thompson joined the group Extinction Rebellion, which has been leading protests throughout the week, resulting in traffic disruptions and the arrest of more than 570 people, per Reuters.

The group has called for nonviolent civil disobedience in an attempt to persuade lawmakers to reduce net greenhouse gas emissions to zero by 2025, reports Reuters.

The actress said she was inspired to partake in the protests after seeing activists across the country this week. Thompson took time at the protest to read poetry celebrating the beauty of the earth.

"This is the most pressing and urgent problem of our time, in the history of the human race," Thompson said. "I have seen the evidence for myself and I really care about my children and grandchildren enough to want to be here today to stand with the next generation." Marianne Dodson

Organized by the United Talent Agency, the United Voices rally "aims to express the creative community's support for freedom of speech and artistic expression, and stand against policies of exclusion and division," the company said in a statement. UTA is one of the most powerful talent agencies in Hollywood, and represents Iranian filmmaker Asghar Farhadi, who is nominated for an Academy Award in the Best Foreign Language Film category. Farhadi said he won't attend Sunday's ceremony because President Trump's executive order banning travelers from seven Muslim-majority countries, including Iran, is "unjust."

Jodie Foster, Michael J. Fox, Wilmer Valderrama, and California Lt. Gov. Gavin Newsom are slated to speak at the rally, and James Franco, Ted Danson, Mary Steenburgen, Seth Rogen, and Aisha Tyler are all set to appear. The rally is being held in lieu of UTA's annual Oscar gala, and the agency said it will also donate $250,000 to the International Rescue Committee and the ACLU. Catherine Garcia
